General research- Description of an assemblage of conchiferan mollusks from the Cambrian Shackleton Limestone (Antarctica) is published by Claybourn et al. (2019).[1]
- A study on Early Triassic recovery of ammonites and gastropods after the Permian–Triassic extinction event is published by Pietsch et al. (2019).[2]
AmmonitesResearch- Dimorphic Indonesian ammonite Macrocephalites keeuwensis is reported from the core of Jara Dome (Kutch district, India) by Jain (2019).[3]
- Description of new fossils of members of the genus Lytohoplites from the Neuquén Basin (Argentina), taxonomic revision of the Lytohoplites species occurring in this basin, and a study on the ontogeny, probable sexual dimorphism and spectrum of intraspecific variability of members of this genus, is published by Vennari & Aguirre-Urreta (2019).[4]
- A study on the intraspecific variation through the ontogeny of the Late Cretaceous ammonite Scaphites whitfieldi from the Western Interior of the United States is published by Klein & Landman (2019).[5]
